I remember there was this teacher at school called Madame. Everyone believed that she had 3 red wigs that she wore in rotation to mimic real hair growth. Stories went round of people who had seen the label sticking out, or the whole wig go squiff.
I don’t think it can have possibly been true but I didn’t realise that until I came to remember it just now. The whole thing reminds me of the The Witches by Roald Dahl, for some reason.
